I just chose the Duracell because I was tired of that had my low batteries in my Funkfernschlüßel, no coverage and long-term durability. Lo and behold, this Durazell does what the advertising promises. She has my keys over twice the range. The car can already be open from significantly further from reach. Also, it opens dependable, which was previously not always the case. So my conclusion is a bit more expensive but quality worth every.
